yaourt alternative needed

[jtmkrueger]

With the death of yaourt new arch instructions will be needed, or people can just build from source (that's what I'm doing). I don't know if you have plans but if you want me to submit a PR that just pulls those arch instructions from the readme I can easily enough.

I am not a Arch user, so I do not know what the current preferred way is to install non-core packages. Feel free to submit a PR with the current preferred way to install chruby under Arch. Ideally, any new instructions should require as few steps as possible.
